The latest generation of Loadall telehandlers for the agricultural market benefit from JCB’s high torque, low emission Ecomax diesel engines along with a host of detailed technological developments, each contributing to more efficient use, easier operation, lower running costs and ultimately, greater productivity. Developed to meet the US Tier 4 Interim emissions standards, the JCB Ecomax engine has no requirement for costly diesel particulate filters (DPF) or for exhaust after treatment fluids, resulting in low cost, efficient operation for customers.
More than simply an engine upgrade, revisions to the Loadall line-up include:
- JCB Ecomax engines with up to 15% more torque and reduced fuel consumption
- High back-off brakes, contributing a 2% efficiency gain
- Button-style gear selection on servo joystick
- Transmission dump integrated into brake pedal
- Variable speed cooling fan, reducing noise and fuel use
- New aggressive styling with revised engine hood and pod
- Modern cab environment for reduced fatigue and enhanced ease of use
“JCB has looked at every aspect of Loadall performance, from the engines to transmissions and hydraulics. We have completed more than 110,000 hours of testing and invested more than $124 million to deliver the most efficient range of engines for our customers, each designed specifically to work with our agricultural machinery,” said Tim Burnhope, Chief Innovation and Growth Officer.
Clean Efficient Power With Reduced Fuel Consumption
JCB’s Ecomax diesel engines incorporate an advanced combustion system (patent pending) that manages emissions within the engine, rather than having to rely on expensive after treatment or a DPF. Through the use of cooled exhaust gas recirculation (EGR), a high pressure common rail injection system using up to 29,000 PSI injection pressures and a variable geometry turbocharger, JCB Power Systems has been able to meet the emissions standards while developing additional power and torque, yet using less fuel.
There are three engine ratings available to agricultural Loadall customers. A 108hp (81kW) engine is standard equipment in the Agri Loadall and in the 526-56. This engine offers 15% more torque and 10% more power than the previous engine, delivering increased performance for the customer.
The Agri Plus comes as standard with the 125hp (93kW) engine and although it offers slightly less outright power, the 125hp (93kW) engine delivers 3% more usable torque across its operating range than the previous 130hp (97kW) engine that it replaces.
The 145hp (108kW) engine is now a standard fitment in the Agri Xtra and the 550-80 Agri Plus.
Similarly, though the range-topping 145hp (108kW) engine offers the same power rating as the previous Tier 3 engine, it delivers 3% more torque and provides up to 5% more useable power in the main operating range. All models deliver average fuel savings of up to 5% compared to the previous machines, resulting in substantial cost savings throughout the ownership period.
Drivetrain Improvements Boost Productivity
In the Agri Plus and Agri Xtra mid-range Loadall models, transmission gear shift selection has now been placed within the head of the main loader control lever, eliminating the need for a twist-grip gear change lever on the steering column while forward and direction control can be operated from either the main loader control lever or the column lever (dependent on model).
This removes the need for the operator to take their hand off the loader control lever during operation, maximizing productivity and comfort. In addition, on the Agri Xtra model JCB has removed the various transmission operating modes, providing operators with a simple choice of auto or manual gear changing modes.
With the transmission controls in the lever head, the optional transmission dump function is moved to the brake pedal. This allows full engine power to be applied to the hydraulic system, without the transmission driving against the brake system, reducing wear and cutting fuel consumption, ideal when undertaking bulk materials handling applications such loading feed wagons. In addition high back-off brakes, which literally pull the brake pads away from the disc to prevent drag, are now standard on all models. They contribute a 2% efficiency gain to the driveline.
This is further improved by reduced transmission oil levels, cutting churning losses and drag within the transmission. This reduction in drag contributes a further 1% efficiency gain.
Bold Exterior Design Preserves JCB Visibility And Serviceability
The revised engine hood and pod now direct cooling air from the top of the front, through the cooling pack and around the engine, to exit at the top of the rear of the hood. This prevents cooling air disturbing dust and debris on the ground below the engine, prolonging air filter life and reducing dust on site for the operator.
However, despite the aggressive new look, complete with updated JCB color scheme, the designers have not had to sacrifice JCB’s legendary visibility across the engine. As there is no bulky DPF or exhaust after treatment to accommodate beneath the engine hood there has also been no requirement to extend the wheelbase or chassis length of the Loadall, as with some competitors, so the machines also maintain their respected maneuverability and tight turning circles.
Improved Cab Environment For Operators
In the cab, the Loadalls feature a completely new instrument cluster and dash layout, with a high resolution LCD monitor. The front dash installation has been restyled for a clearer layout and the cab heating and ventilation system now features a seven-speed fan, providing greater control for the operator. The top half of the cab door now comes with a revised slam latch mechanism and door ajar facility to ensure that the window stays open if required.
“With the latest generation of agricultural Loadalls, JCB has once again moved the telescopic handler market forwards a giant step,” says Mr Burnhope. “This advanced range, with clean, efficient JCB Ecomax engines, will ensure that JCB remains the world’s number one telescopic handler manufacturer.”
